Other games should take notice

I come from a long history of gaming. All platforms from Pokémon to call of duty and every where between. I’ve been playing this game for almost 7 days and I feel like The people behind the game have played games there whole life to. Because I haven’t once want to stop playing this game yet I still have to go to work and take care of my kids so for this game to play for me as I step away. Is amazing! Because at the root of every game there is always a race to beat it the fastest. The race to rank the highest. The race to build characters. The race to build the perfect team. And this game helps the players that can’t play 100% of the time. Stay in that race and keep the thrill alive.

Keeps crashing every now and then, don’t know what’s the problem

I’ve been playing this for about 3 months now, and prior to and after the recent update, there have been many instances of the app crashing while I’m in mid-battle and I keep losing out on the rewards especially when I’m near the end of a boss fight and it crashes on me and says I haven’t defeated it yet. I don’t know what the problem is but if it’s just me then I would assume it’s the iPad that needs a fix, but I don’t know if others can play it normally or have similar issues. Anyways, developers, if you are reading this, please look into whether or not if it’s the new update that has a bug or something. If it’s not something that others are getting, then please send a reply so that I know it’s not a multi-user issue.

Started at the top, now we are here

I hope this review makes it to a developer or someone! I really really enjoyed playing this game. I started off very well, summoning three Nat 5s before hitting level 25. All was great. Then an update hit, and as if by magic, one of Nat 5s was gone. Not sure if it was a bug, hack, or something else.
So I submitted a complaint to the game developers via the FAQs in the game. I even included screenshots of me having this Nat5. I was met with silence. I didn’t receive a reply at all. To this day it has been a month. No matter how many times I sent a message, all I received was an automated message saying they will get back to me.
I find this unacceptable. The lack of customer service is what drove this rating to 1 star. I spent money on this game to, and was going to spend a little more to progress faster. However, since this experience, I have stopped playing. As much as I wanted to continue I could not knowing the lack of customer service.
